Other Experimental

Solutions of fluosilicates are sensitive to hydrolysis in alkaline medium. In the presence of acid, fluosilicate solutions release silicon tetrafluoride. The thermal decomposition of fluosilicates takes place with release of gaseous silicon tetrfluoride and formation of the solid fluoride. /Fluosilicates/
